Small Cap 2017–2019: 130% Up, Then 55% Down — The Complete Cycle
Indian small cap stocks completed one of the most dramatic boom-bust cycles in market history between 2016 and 2019. Every investor in small cap funds lived through it.
Nifty Smallcap 100 rose 130% from early 2016 to January 2018, attracting massive inflows near the peak. It then fell 55% over 20 months. The full cycle illustrated both the opportunity and the psychological demands of small cap investing.
The Bull Run: 2016–2018
After several years of underperformance following the 2008 crash, Indian small cap stocks entered a powerful bull phase in 2016. The macroeconomic backdrop was supportive: demonetisation had displaced cash into the financial system, GST was creating a formalisation of the economy that benefited organised small companies, and FII flows were positive. Small cap companies were growing faster than large caps.
| Period | Nifty Smallcap 100 | Nifty 50 | Small Cap Premium |
|---|---|---|---|
| Jan 2016 – Jan 2018 | +130% | +40% | +90% outperformance |
| Peak (Jan 2018) | 8,800 | 10,600 |
Monthly SIP flows into small cap mutual funds rose from ₹200–400 crore in 2015 to ₹3,000–5,000 crore per month by late 2017. The funds that had been generating 30–40% annual returns were attracting the most money — precisely as their underlying stocks were reaching expensive valuations.
The Trigger: SEBI Recategorisation and NBFC Crisis
In October 2017, SEBI announced a sweeping recategorisation of mutual fund schemes, which came into effect in June 2018. Under the new rules, small cap funds were mandated to hold at least 65% in small cap stocks (251st company and below by market cap) at all times. Previously, fund managers had flexibility to shift to mid or large cap stocks when small cap valuations looked stretched. That flexibility was removed.
The NBFC crisis (IL&FS default in September 2018, followed by DHFL and others) hit small cap companies particularly hard — many had relied on NBFC funding for working capital. The credit crunch in the NBFC sector rippled into small cap earnings. By September 2019, Nifty Smallcap 100 had fallen 55% from its January 2018 peak.
The SIP investor who started in late 2017
An investor who started a ₹10,000/month small cap SIP in October 2017: • Started investing near the peak at high valuations • Watched paper losses accumulate for 22 months • By September 2019: portfolio down 30–40% despite 22 months of SIP contributions • The test: could you continue SIPs through this? Most could not.
The Recovery: Spectacular for Those Who Stayed
From September 2019 onwards — and supercharged by the COVID crash bottom in March 2020 — small cap staged one of the most explosive recoveries in Indian market history. Nifty Smallcap 100 rose from its September 2019 level by approximately 250% to December 2021. Investors who had held through the brutal 2018-19 period and continued SIPs were rewarded enormously.
| Scenario | Corpus Position (Dec 2021) |
|---|---|
| Stayed invested Jan 2018 through crash and recovery | Significantly positive — full cycle delivered positive returns |
| Sold at September 2019 bottom | Crystallised 55% loss; missed 250% recovery |
| Stopped SIPs during crash, restarted at 2020 highs | Missed cheapest accumulation months; lower unit count |
| Started fresh SIP at Sep 2019 bottom | Exceptional returns — caught the entire recovery |
Key Lessons
- →Small cap investing requires a minimum 7-year horizon because a complete cycle (peak to trough to recovery) can take 3–5 years
- →Peak inflows into small cap funds are a reliable contrarian indicator — the time of maximum retail enthusiasm typically precedes the crash
- →A 55% drawdown in small cap funds will test even the most disciplined investor — position sizing must account for what you can emotionally survive
- →SEBI's recategorisation removed the active manager's flexibility to reduce small cap exposure at peaks — this increased the concentration risk of small cap funds
- →SIP continuity through the trough is the most valuable discipline in small cap investing — stopping SIPs during the worst months means missing the cheapest accumulation
- →If you cannot stomach watching your portfolio fall 50% over 22 months without exiting, small cap is not the right category for you regardless of your return expectations
